uncaught exception ui engine accessed without holding the event lock

symptom: uncaught exception: ui engine accessed without holding the event lock error shows, messages in bbm are not viewable until hard reset performed.

i have experienced this error with both of the two 8900s i have owned. this one is a refurb and began giving the error shortly after i restored from my old device backup. this leads me to believe that something i have done, somewhere, is causing this error to occur.

i have backed up, wiped and restored on both devices and on the current device i have just reinstalled the os and all applications.

i am on the rogers wireless network in canada, i have the current os freshly installed and here is a list of the few 3rd party applications i am using (note: this error occurred on my old device before i installed any third party apps.)
